Brucella spp. Virulence Factors: Review.

Brucella is one of the pathogens that spread globally, these bacteria are transmitted by livestock and their products, and their infections are chronic infections due to the presence of many virulence factors of this bacteria that protect these bacteria from the body's defenses and immunity, and from this endotoxin (Lipopolysaccharide) as well as the secretion of various enzymes like Urease, Superoxide dismutase, and Catalase. Brucellosis leads to greater growth of lymph nodes, liver, and spleen. Brucella's pathogenicity relies on its capacity to replicate, live inside the macrophages and virulence factors.
